I liked the response from US Senator Ron Wyden, who has consistently made the same point against both the Obama and Trump administration on this issue:
From the Senate floor on Tuesday, Sen. Ron Wyden, D-Ore., responded to Barr’s remarks in New York calling it an “outrageous, wrongheaded and dangerous proposal.”
Wyden said Barr wants to “blow a hole” in a critical security feature for Americans’ digital lives by trying to undermine strong encryption and advocating for government backdoors into the personal devices of Americans. He said strong encryption helps keep health records, personal communications and other sensitive data secure from hackers.
Effectively banning encryption in the U.S. by not allowing companies to provide unbreakable encryption, doesn’t prevent it existing and flourishing elsewhere, and only makes Americans less secure against foreign hackers, Wyden said.
“Once you weaken encryption with a backdoor, you make it far easier for criminals, hackers and predators to get into your digital life,” Wyden said.
